Specification of Letters Patent.

Patented May 27, 1913.

Application filed August 16, 1912. Serial No. 715,324.

clear, and exact description.

This invention relates to multiple cash registers and has moreparticular relation to machines of the type in which a plurality oftotalizers are provided to enable a segregate analysis of transactions.7

The principal object of the invention is to provide an improved form ofmechanism for effecting the selection and actuation of any desired oneof a plurality of totalizers.

The particular form of machine to which the present improvements havebeen shown as applied is that shown in Letters Patent of the UnitedStates issued on July 1st, 1902, to Thomas Carroll and numbered 703,639.The machine shown in that patent and as illustrated in several views ofthe present application, is provided with a plurality of tion betweenany one of the totalizers and the common actuating racks, by themovement of a selecting lever. After the desired totalizer has beenpositioned for operation, the machine is then ready for general opera:tion. Upon the operation of the machine the rotatable carrier, which, asbefore stated, is mounted ina slidable frame, is elevated so as to causean operative engagement of the positioned totalizer with the actuatingracks. Upon the completion of an actuation of the totalizer in the entryof the amount set up on the keyboard, the totalizer frame is againlowered to disengage the actuated t-otahzer from the actuating racks.

Various forms of mechanism have been provided for elevating andcontrolling the movements of the totalizer frame. In United StatesLetters Patent issued to R. H. Riddle on November 7th,1905, and numbered803,714, there is shown a form of elevating and controlling means forthe rotatable carrier which permits of the disabling of the liftingmeans during an entry-of a special transaction, such as char e and paidout As is well known in the art to which the present applicationpertains, when a machine of this class is put to practical use it isgenerally desired to have entered upon the totalizer only those amountswhich represent the actual amounts in cash which are taken in on cash orreceived on account transactions and not upon the charge or paid outtransactions. In handling the last two classes of transactions it iscustomary to employ mechanism for throwing out the totalizer so that theamount indicated and recorded will not be entered upon the totalizer.The construction shown in the Riddle patent above mentioned is veryeffective in performing the function for which it was originallydesigned, but in general use it was found that certain manufacturingproblems arose which rendered it advisable to design the improved formof mechanism involved in the present application. I

A further object of the present invention is to provide a new andimproved form of detent mechanism operated and effective in connectionwith the depressible keys. As shown, and hereinafter described inconnection with certain figures in the drawingsof the presentapplication, the form of detent mechanism which has been in common use.on machines of the type to which the present invention has been shown asapplied, While bein very eflectivegin performing the desire function,the operation of the keys was rendered quite hard. It was found that agreat deal of power was required in the depression of the desired keysin registering and also the operation of the keys in the. mannerhereinbefore mentioned resulted in, the breakage of a large number ofthe key springs which are used in forcing the keys out to normalposition at the end of each operation of the machine, when the detentsare operated to release thekeys. An improved form of detent mechanismhas therefore been providedwhich enables thedepression of the amountkeys by the application of a greatly decreased amount of requit-ed.power and also reduces to a great extent the breakage in the key springshereinbefore mentioned.

A further object of the invention is to provide a new form of latch forthe operating mechanism of the machine which is directly I tioncdtotalizer with the actuating racks controlled by the detent mechanismand thereby placed under control of the keys. In connection with thislatching means there are provided devices controlled by the movements ofthe cash drawer whereby the machine may be adjusted to prevent anoperation of a key to release the machine while the cash drawer is inopen position. Devices of a similar nature have been designed for use inother machines of this character, but the form of mechanism herein shownand described as forming a part of the present invention is a decidedimprovement over the mechanism heretofore employed. The mechanism isrent lered adjustable and is placed under control of a key controlledlock which is accessible only to the proprietor of the store in whichthe machine is used and whereby the mechanism just referred to may be soadjusted as to permit of the. release of the machine by the depressionof the keys regardless of the position of the cash drawer; or preventthe operation of the keys while the cash drawer is open; or, third, completely to lock the amount keys against de pression and therebycompletely lock the machine.

A further object of the invention is to provide a new and usefulimprovement in the alarm mechanism whereby the striking of the usualform of hell is placed under control of a key controlled lock, theadjustment of which to throw out the alarm mechanism willtend to preventthe striking of the bell by the bell hammer upon all operations of themachine subsequent to the adjustment.

A further object of the machine is to providean improved form of motorcontrolled fnechanism whereby the clerks keys release the motor toactuate the machine and a further operation of the machine is preventedif an attempt is made to hold a key depressed at the completion of anoperation.

lVith these and incidental objects in view, the invention consists incertain novel features of construction and combinations of parts, theessential elements of which are set forth in appended claims, and apreferred form-of embodiment of which is hereinafter described withreference to the drawings which accompany and form part of thespecification.

Of said drawings: Figure l is a left hand view of the machine showingsetting mechanism for positioninga desired totalizer and an improvedform of lifting mechanism for establishing an operative engagementbetween a positioned totalizer and the actuating racks. Fig. 2 is adetail View of part of the mechanism shown in Fig. 1 with the additionof certain key controlled means for disabling the operation of thetotalizer frame to effect engagement of the positherefor. Fig 3 is a.detail front view of a lock for controlling the operation of the keysand machine while the drawer is open or closed as desired. Fig. 4 is across section of a machine of the ty ac to which the presentin'iprovements are siown as applied and showing applied thereto theimproved form of alarm mechanism and controlling means therefor. Figs.5, 6, and 7 are detail views of detent mechanism which is old and wellknown in the art. Figs. 8 and 9 are detail views of an improved form ofdetentmechanism which forms a part of the present invention. Fig. 10 isa cross section of the machine showing the locking mechanism for thekeys and operating mechanism of the machine under control of the cashdrawer and the key controlled lock. Figs. 11 and 12 are views of themechanism for controlling .the operating motor and the means forpreventing a second operation of the machine while the motor controllingkey is held depressed.

The type of machine to which the present improvements are shown asapplied is old and well known at present and mach nes of this typegenerally comprise a plurality of keys 30 which act differentially tocontrol the adjustment of an operating member 31. The keys 30 arearranged in banks and the number of banks provided is dependent upon theregistering capacity desired of the machine. It is, of course,understood that there is an operating mcn'iber 31 provided for each bankof keys 30 and the members 31 act differentially to adjust theintermediate gears 32 and through the medium of said gears actuate theindicating mechauisn'i 33. In the Carroll patent above referred to. andas shown in Fig. 4, the gears 32 are fast on the inner ends of a seriesof nested sleeves 34 which extend to the left hand end of the machineand carry on their outer ends a plurality of actuating rack segments(see Fig. 1) adapted to actuate any desired one of a plurality oftotalizers 36 carried by a rotatable frame 37 pivoted on a short shaft38 mounted in a sliding frame 39. The frame 39 is mounted to slide inguideways 40 so as to carry the positioned totalizer into operativeengagement with the actuating racks 85.

The means for placing any desired one of the totalizers 36 incooperative relation with actuating racks 35 comprises a setting lever41 pivoted at 4-2 and formed at its lower extremity with a rack segment43 constantly in mesh with a segment 41 fast on a short shaft 45. On theshaft 4:5 is also rigidly mounted a segment; 46 meshing with a pinion 47fast on the carrier shaft 38. The lever 40 is capable of adjustment inany one of nine different positions as shown in Fig. 1 and throughthecennections just described will" tend to rotate the carrier 37 tobring any desired one of the totalizers into cooperative relation withthe actuating racks. The slidable frame 36 is adapted then to beelevated to establish an operative engagement between the positionedtotalizer and the actuating segments by the improved form of liftingmechanism shown in Figs. 1 and 2 and which forms an important part ofthe present invention. I

The frame 39 is slotted near its upper end to surround a rotary shaft 48which is adapted to be given a single rotation at each operation of themachine. Fast to the shaft 48 is a cam disk 49 which acts to raise theframe 39 to effect an operative engagement between the positionedtotalizer and the operating segments just prior to the difi'erentialadjustment of the latter. Mounted adjacent the sliding frame 39 is asmall sliding plate 50 which is slotted near its upper end to surroundthe shaft 4:8 and slotted at its lower end to surround a stud 51 carriedby the frame 39. Near its upper end the slide 50 carries ananti-friction roller 52 adapted to coiiperate with a camming flange 53carried by the cam dish 49. The stud 51 carries an anti-friction rollerwhich is adapted to cotiperate with the periphery of the earn disk d9.

When the parts are in the position shown in Fig. land the shaft 48 anddisk 49 are rotated in the direction of the arrow shown, a bevel end 54of the camming flange 53 will engage the under side of the roller 52 andthereby raise the plate upwardly and rearwardly until the roller 52rides on the outer surface of the camming flange 53.

When the plate 50 is so elevated it will, through the medium of the slotformed therein and cotiperatin with the stud 51, elevate the frame 39 alike distance which is suthcient to cause an operative engagementbetween the positioned totalizer and the segments 35. The plate 56 andframe 39 will be held in elevated position during the operating strokeof thaope'rating segments 35 and immediately following the completion ofthe operating stroke of all the segments, the frame 39 and vslide'fit)will be forced downwardly by reason of the enga ement of a high part ofthe periphery of t e cam dish 49 with the roller carried by the stud 51.

it will readily be seen that if it were desired to have a totalizer moveinto operative engagement with the operating scents at every operationof the machine, the intermediate connections com; rising the roller 52and sliding plate 50 mig t well be dispensed with and the cam disk 49might then be permitted to cooperate directly with the roller on-thestud 51 to elevate-and depress the frame 39 at every operation of themachine. However as stated in the setting forth of the objects of thepresent invention, it is at times desirable to operate the machine toindicate and print an amount without recording the same upon any one ofthe to.- talizers. In order properly to indicate the complete record itis, of course, necessary to position the lever 41 and consequently. thetotalizer carrying frame as is well known in machines of this type.Means are provided, however, whereby'during those operations when thetotalizer is not to be actuated, the positioned totalizer is thrown outso that no addition will take place upon the same. As hereinbeforestated, this operation occurs in recording amounts appropriate totransactions such as charge and paid out. It

is in these operations when the elevating mechanism for the totalizerframe is not to be efiective that the employment of the slidin late 50is rendered necessary.

I e plate 50 is normally held in a position shown in Fig. 1 by reason ofthe engagement of the lower end of a slot 55, formed ina link 56, with astud 57 carried by the slide 50 at its lower end. The link 56 ispivotally connected at its lower end at 58 to an arm 59 fast on a rockshaft 60. A spring 61 is provided for holdingthe link 56 and plate 50 inelevated position, one end of said spring being connected to the pivotalpoint 58 and the other end being connected to a pin 62 fast on the frameof the machine. As shown in Fig. 2 the shaft extends to the right andcarries near its inner end, an arm 63 carrying a pin 64 at its upperend, and also an arm 65 which is pivotall connected to the rear end of alink- 66, he forwardend of link 66 is pivotally connected at 67 to alate 68 pivoted loosely upon a shaft 69 and having formed in its upperend notches 70 which cooperate with P111871 carried by the keys 72 whichare appropriate to charge and paid out transactions. When either of thekeys 72 is depressed its pin 71 is adapted to engage its appropriatenotch 76 and rock the plate 68 about its pivotal point 69. The roclringof the plate 66 will force the link 66 rearwardly and through the mediumof the arm 65 will rock the shaft 60 in a counter-clockwise direction."When the shaft 60 is rocked in this manner, it will draw the link 56downwardly against the tension of spring 61 and will also rock the arm63 to cause the pin 6% carried thereby to move in the path of a flange73 carried by an oscillating scent M. The segment 74 is fast on the rockshaft which as before stated, is oscillisted at each operation of themachine and upon the oscillation of the shaft 60 and segment 74, whenthe arm 63 and pin 64 have been so moved, the lower bevel end 75 of theflange 73' will engage the pin 64: and cause an additionalcounter-clockwise rocking movement of the shaft 60. This will cause anadditional downward movement of the link 56 and through the slot and pinconnection of said link 56wit-h the plate it will tend to draw the plate50 downward so as to cause the roller 52 to move slightly downward andout of the path of the bevel face 54 of the camming flange 53 carried bythe cam disk 49- The roller 52 will then cooperate with the inner curvedsurface of .the

camming flange 53 and as said surface is concentric to the axis ofrotationfof the cam disk 49 the plate-50 will be held in loweredposition and consequently the frame 39 will not be elevated. As soon,however, asthe operation of the machine is completed, the

keys 72 will spring outwardly under the action of their key springs 82and the parts 56, 59, 60, 63, 65, 66, and 68 willbe allowed to move backto normal position under the action of the spring 61, when the flange73- will have moved out of engagement with the pin 64'to permit therestoring movement of the parts just referred to. If the machine isoperated with neither of the keys 72 depressed, the pin 64 will remainin the po sition shown in Fig. 2. Consequently when the segment 74 isoscillated-as above" described, the forward surface 76 of the flange 73"will ride to the. rear of .the pin 64 and thereby prevent any rockingmovement. of the shaft to disable the totalizer frame. elevating meansduringan' operation of" the machine; Whenever an operation oflthemachine isbegun with the pin 64 in the-po sitionshown in Fig 2 thedisablingflmechanism will belocke'd "against movement and therefore thetotalizer frame 39 will: beele-- vated to, cause an operative engagementbetween the positioned totalizer and the operatingse'gments 35, Wheneverthe operation of the machineis begun, however,with the pin 6% moved to.the left in Fig. 2, in which moved position it will be engaged and movedstill farther-to the left by the flange 76,the plate 50" will bedrawndownward thereby to cause the roller 52 to pass out of cotiperativerelation'with the flange 53 and consequently the continued operation ofthe hin will not efi'ect an: elevationsof the so frame 39.

Key detent mohanism.- Meansareipro? vided for locking the keys 30 indepressed position While the 'difierential adjustment of the operatingmembers 31-"is'beingefi'ected;

The locking mechanism for holdings-the key's 30 indepressed position hasgenerally com-. prised a locking member ZZ"pi voted on the central shaftof the machine and formed on its free end in the form of an areconcentric With the arc in which the keys were placed' The form oflocking member 77 which. is shown in Figs. 5, 6, and 7 is the form whichhas come into common'use inmachines of this type and are shown so as tobring out clearly the idea of the improved form shown so will beheld depssed;

It will b gan that when. s employedfimthe fern-shew 5 weaver in Figs. 8and As shown in Figs 5 and .9, the keys are formed with a diagonalgroove 78 and the inner end of each key is formed with 'the'bevel face79. The curved forward face of the member 77 is formed with lugs 80, oneof which isprovided for 80 are formed with a smaller outer lug 81 for apurpose hereinafter described. The

keys 30 are normally in position shown in Fig. 5 and are guided in theframe of the .machine-so thattheir inward movement is 'fixed'and in the.direct line of a radii of the arc in which the keys are placed. .Whenany one of the keys 30 is depressed against the tension of a spring82,the inner bevel end 7 9 of the key'30 will. engage the face 820 of thelug 80 which is immediately-in its path. The continued depression of thekey 30 will c'ausethe detent to. rock about its pivotgin the directionof the arrow shown until the key is forced completely into the positionshown in Fig; 6. In this position the lug'j 8Q immediate] adjacent theone which was engaged by t e key will haveen tered the-slot 7 8 formedin the key and any the lug 81 striking ey as shown in Fig.

and 6'it isnecessary to'h' e the inner ends of the undepressedke'ystcleai of the lugs 80 so as to. permitfreejmoveinenhnf the mem ber77 when any-one of the keys is depressed.

Consequently in order to move the inner end of the key inwardly to anextent sufiicient innate? to bring it in a posit-ion to control thedifferential adjustment of the operating member 31, it will necessarilyrequire quite a long inward depression of the desired key. During thedepression of the selected key the key spring 82 will be compressed tothe position shown in Fig. 6. It will readily be understood that a keyspring which is re peatedly compressed to the extent shown in Fig. 6will be greatly weakened under continued use of the machine and it hasbeen found in practice that the spring when so depressed will frequentlybreak after the machines have been in use only a short period of time.It has therefore been found necessary to so construct and arrange thekeys 30 and the locking members 77 relative to each other as to shortenthe required inward movement of the desired keys. With this idea in viewthe members 77 have been slightly changed by providing a curved cut awayportion 87 which is formed by cutting away a small portion of the lugs80 and 81. The keys 30 are then lengthened so that when in. normalposition their inner bevel ends 79 will extend beyond the extremeouterline of the curved forward surface of the locking member 7 7 andconsequently the inward movement of the key required to bring such innerend into the position to control the difi'erential adjustment of theoperating member 31, is considerably de creased as compared with theconstruction shown in Fig. 5. With reference to the constructions shownin Figs. 5 and 6, it will be remembered that it was pointed out to benecessary to have the inner ends of the keys clear of the lugs 80 and 81when the keys are not depressed. When the key is con structed as shownin Fig. 8 with the inner end of the key projecting inwardlybeyond theouter curved surface of the members 77 it necessitates the cut awayportion 87 so as to provide sufficient clearing to permit of thenecessary elevation of the members 77 when any one of the keys isdepressed. .By lengthening the keys as shown in Fig. 8, as above stated,it requires a greatly decreased extent of inward movement to bring theinner end in the path of the operating member 31 and consequently thespring 82 will only be compressed to the extent shown in Fig. 9. It willreadily be seen that this difi'erence in compression of the springs 82will tend greatly to prolong the life of said springs.

By thelengthenmg of the keys a more lt will likewise be seen that the'shortening of the stroke of the keys 80 and inner end 7 9 of the key isin position immediately to contact with the incline wall 820 cf thedetent lug 80 cooperating therewith so that in connection with the useof a light spring 82 a uniform and light pressure is attained throughoutthe entire stroke of the key. With the old construction, as shown inFig. 5, it will be seen that practically the first half of the stroke ofthe key is an idle movement, with the exception of compressing thespring, and during the last half of the stroke the extra work of rockingthe detent- 77 is added thereto, which requires an uneven and thereforean undesirable key pressure. To the casual operator this light anduniform key action might not appear to have very great advantages, butin establishments where all of the transactions are run through themachine by one or two operators, such for instance as would be the casein the well known and extensively used pay cashier system this improvedkey construction has advantages of great merit as it enables the clerkto operate the machine faster and with less fatigue, which advantagesare in addition to those heretofore described relative to the prolongingthe life of the springs.

Key release.lt is customary'in machines of the presenttype to providemeans whereby when a key is depressed in error the same may be releasedbefore an operation of the machine is begun. This means comprises thefollowing constructions: It will be recalled as hereinbefore stated thatwhen a key is depressed the detent element 77 is elevated to an extentsuihcient to permit the slide or looking late 84 to spring rear wardlythereby bringing a shoulder formed thereon beneath the lower forward endof the detent member to hold the latter elevated in locking position. Itwill therefore be seen that in order to release the depressed key itwill be necessary to draw the plate 84 forwardly against the tension ofthe spring 86 thereby to ermit the depressed key to spring outward underthe action of its s ring 82 and permitting the detent member 7 to dropdown to normal position. The forward movement of the plate 84 is edectedin the following manner. At its forward end each of the plates 84:carries a pin 88. Adjacent each of the pins 88 is a pin 89 mounted on arock shaft 90 which extends across the front lower portion of themachineand has fast on its right hand end a small operating lever 91. Avspring 92 normally holds the lever 91 and shaft 90 and pins 89 in theposition shown in Figs. l and 11. A pin 93 fast on the frame of themachine normally standsin the path of a projection 94. carried by thelever 91 to limit the action of the spring 92. When it is desired torelease any key which is depressed in error it is necessary merely topress down on the forward end of the lever 91 thereby rocking the shaft90 in a counter-clockwise direction to cause the pins 89 carried there-'by to engage the pins 88 mounted on the plates 84. The continued rockingmovement of the shaft 90 will cause the engagement of the pins as statedto draw the plates 84 forwardly to the left as shown'in Fig. 4 so as towithdraw the locking shoulder from beneath the detent member 77 therebyreleasing the depressed keys in .the manner hereinbefore stated.

Machine Z0clcs. -l[t is customary in machines of the present type toprovide mechanism whereby the operation of the machine will be placedunder the control of a' bank of keys containing either the keys whichare assigned to special transactionsor to the various clerks operatingthe machine. The

mechanism-is generally arranged so that it will be necessary to operatesome key in this bank before the machine may be operated. In Fig. 10there are shown mechanisms for performing this function. As will henoted, the detent member 77 appropriate to the keys 30 of thisparticular bank carries a roller 95, near its upper end, which normallystands against one arm 96 of a three armed lever 97 fast on a short rockshaft 98 and having on its rearwardly extending arm a locking projection99 which'in the normal position of the lever 97 engages in a notch 100formed in the disk 101 fast on the rotation shaft 48. By reason of theformation of the notch,100 in said disk 101 it willv readily be seenthat the shaft 48 is locked againstrotation until the lever 97 is rockedabout its pivot. The lever 97 has the downwardly arid forwardlyextending arm 102 to which is attached one endof a spring 103, the otherend of which'is fastto a pin 104- fast on the frame of the machine. Asthe locking member/Z7 is moved upwardly when, one of the keys30 isdepressed, it will read- 1ly be seen that through the engagement of theroller 95 with the arm 96, as soon. as

the detent member '77 is" raised, -itwillefiect a rocking movement ofthe lever 97 against the tension of the spring 103 thereby with drawingits locking pro ection 99 from engagement with the notch 100 of thelocking disk 101. Mechanism. is further provided whereby the specialkeys 30 just describedare locked against operation while thecash' draweris in open position. In machines of this type it is customary to providea cash drawer which is released upon each opera tion of the machine andforced outwardly,

under the action of a springgto expose the same for the purposeof'making change or receiving the money'tendered, lit is desire able attimes to have mechanism so arranged that it will be necessary to closethe cashf 98 again to weave? contained in the drawer may be had. In

order to perform this function there is provided a bell crank lever 105pivoted at 106 to the frame of the machine and having a downwardlyextending arm adapted to engage the rear end of the cash drawer 107.

The downwardly extending arm of the bell crank 105 is formed'in twoparts 108 and 109 which are pivoted together atllO and pro.- vided withan adjustable connection'lll so that the engagement of the cash drawer107 with the downwardly extending arm of the bell crank may be properlytimed. The bellcrank l05 has a forwardly and upwardly-em tending arm 112formed'at its forward end with a locking hook113. The mechanism 1 asshown in Fig. '10 is the position which will be assumed by the same whenthe cash drawer 107 is locked in non-exposed position. When the cashdrawer is released.

upon an operation of the machine and allowed to move outward to exposedpos tion in the manner hereinbefore referred to, the

bell crank lever 'is caused to rock about its pivot 106 underthe actionof a spring bell crank 105 and the other end connected crank 105 is sorocked about its pivot 106 will move forwardl and engage a similarlyformed hooked en 116 formed on a lever 117 which is fast on the rockshaft 98 which carries the locking lever 97. The bell crank lever 105will remain in this position as long as the cash drawer remains inexposed position:, Consequently it will readily be seen that thedepression of the key 309 will be prevented by reason of thelockingengagement of the hooks 113 and 116, as it will be recalled thatwhen the key 30 is depressed the roller 95 carried by the lockingmemberv 95 114 one end of which is connectedlto-the to the main frame at115. Wh'en-theQhell not 77 appropriate to the depressed key .will

tend to rock" the lever 97 and its shaft 98 in aclockwise direction.Such movement,how-

ever, .is prevented byreason of the locking engagement of the two hookedportions 113 and 116. It is therefore necessary again to close the cash"drawer 107 before the keys 30- just referred to may again be depressed.The closing movement of the cash drawer will cause the bell crank leverto be rocked about its pivot in a counter-clockwise direction againstthe action of-the spring 114 thereby to disengage the hooked portion 113from the hook 116 and releasing" the shaft permit the depression of oneof the keys 30.

In certain. uses of machines of this 100 the forward hobkedendllS of itsarm 112 it is often desirable to'disable the mechanism just described soas to permit of an operation of the machine during rush hours withoutclosing the cash drawer after each operation. In theperformance of thisfunction the mechanism described is placed under control of a keyoperated lock118 located at the front of the machine just beneath thekeyboard. The lock 118 may be of any desired form employing a detachablekey which may be retained in the possession of the proprietor so as toplace it solely under his control. .The lock 118 is capable of threeadjustments: first,.to permit of an operation of the keys only when thedrawer is closed; second, to permit of the keys 30 being operatedrl'legardless of the position of the drawer, a third, to entirelydisable the keys. Th'e lock 118 controls a shaft 119 which extends'rearwardly in the machine and is supported at its rear end by plate 120which is mountedon the shaft 106 and pin 115.. Near its rear end theshaft 119 carries a locking arm 121.;which is adapted to cooperate withthe projection 122 formed on bell crank 105. In the first position ofthe lock as above noted, the arm 121 is above the .path of theprojection 122 thereby permitting a freerocking movement of the'bellcrank lever 105 about its pivot 106. If, however, it is desired tooperate the keys regardless of the position of the cash drawer thel0ck,118 is adjusted to its second position thereby rotating the shaft119 to an extent suflicient to bring the arm 121 carried thereb into thepath of the projection 122. When i e cash drawer is then released, therocking movement of the bell crank 105 under the action of the spring114 is revented by reason of the engagement of the projection 122 withsaid arm 121. It will thus be seen that the shaft 98 and locking lever97 may be rocked by the depression of'a key to release the machineregardless of whether the cash drawer is in exposed or unexposedpositions. If it isdesired to lock the machine against operation bydisabling the keys 30, the lock .gis adjusted toits thirdposition so asto bring a plate 123 carried by said lock into a posi tion where it willstand just above the forward end of an arm 124 fast on the shaft 90.Previous to the time of adjusting the lock 118 to the third position, asjust referred to, it is necessary to give the shaft 90 a slight rockingmovement by pressing down on the operating lever 91. This will withdrawthe arm 124 fromthe path of the plate 123 and permit of the ad'ustmentof the latter to its third position. Vhen the lever 91 is then releasedthe return movement of the same together with the shaft 90 under theaction of the spring 92 is prevented by reason of the engagement of thearm 124 with the plate 123. When the shaft 90 is rocked, as justdescribed, it will readily be see th t the pins 89 carried thereby willengage the pins 88 carried by the sliding locking plates 84 and drawsaid plates 84 slightly forward against the tension of the springs 86.\Vhen the lock is then adjusted to the third position and the lever 91is released it will readily be seen that the prevention of return ,ofthe shaft 90 to normal position will also prevent the rearward movementof the plate 84 to normal position, and if a key 30" is then depressedin an attempt to operate the machine, it will readily be seen thatalthough the key is free to be depressed it will not be locked indepressed position because of the fact that when the detent member 77 israised by the depression of the key, the plate 84 will not springrearwardly to hold the detent in elevated position; consequently whenthe pressure is removed from the key, its spring 82 will tend to throwit to outer normal position and'the detent 77 will drop back to normalposition Alarm controlling mechanism.+In Fig. 4' is shown the alarmmechanism which is adapted to give an alarm at each operation of themachine. This alarm mechanism comprises a gong 125 which is adapted tobe struck at each operation of the machine by a hammer lever 126 pivotedat 127. The lever 126 is forced to rock about its pivot under the actionof a spring 128 which is interposed between a rearwardly extending arm129 formed on said lever and a standard 130 mounted on the frame of themachine.

The hammer 126 is normally held away from the gong 125 by a pin 131mounted on a disk 132 fast on a shaft'133 which is adapted to be given asingle rotation at each operation of the machinejn the direction of thearrow. It will be seen that when upon the operation of the machine theshaft 133 is rotated in the direction of the arrow the 4 pin will passbeyond the end of the arm 129 formed on the hammer 126 and consequentlythe spring 128 will act to throw said hammer lever 126 about its pivot127 and cause it to strike the gong 125. Upon the. completion of therotation of the shaft 133 and disk 132 the pin 131 will again engage thearm 129 of the lever 126 and rock said lever about the pivot 127 againstthe tension of the spring 128 thereby withdrawing the hammer 126 fromcontact with the bell 125. I

It is at times desirable to prevent the constant ringing of the bellduring rush hours and means are therefore provided for disabling thestriking mechanism for the bell, just described. This means comprises abell crank plate 134 pivoted at 135 to the frame of the machine andhaving pivoted upon one of its arms a locking pawl 136 which is normallyspring drawn to the po' sition shown in Fig. 4. The plate 134 is adaptedto be rocked by a lever 137 pivoted at 138 tothe frame of the machineand bifurcated at one end to straddle a pin 139 carried by the bellcrank 134. The lever 137 has formed at its forward end a flange 1138 inwhich is formed a slot surrounding a pin 139 carried by the rotary drum.of a key lock 140. If it is desired to disable the alarm mechanism it ismerely necessary to operate the lock 140 which will rock the lever. 137about its pivot 138 in a counter-clockwise direction, which moven'ientis transmitted to the bell crank plate 134 which is rocked about itspivot 135 in a clockwise direction causing the pawl 136 carried therebyto engage a pin 141 carried by the bell hammer 126. This movement causesa slight rocking movement of said pawl 136 about its pivot.

Upon the operation of the machine immediately succeeding this adjustmentof the lock 140, the rotation of the disk 132 will cause the pin 131 togive a slight additional rocking movement of the hammer lever-.126 aboutits pivot 127 in a clockwise direction thereby raising the pin 141. Whenthe pin 141 is so raised the pawl 136 will spring back to nor- -malposition relative to the bell crank plate 134 thereby causing the upperend of said pawl 136 to pass beneath the pin 141. When the bell hammerlever 126 is then released by the pin 131 passing beyond the end of thearm 129 the lever 126 will spring downward under the action of thespring 128 but the striking of the bell by said lever 126 will beprevented by reason of the engagement of the pin 141 with the upper endof the pawl 136. Upon all subsequent operations it will be seen that thepin 141 will constantly strike against the pawl 136 and the sounding ofthe alarm will be thereby prevented until the lock 140 is again adjustedto normal position, in which position the pawl 136 will be withdrawnfrom the pat-h of the pin 141.

Motor controlling mecham'sm.-It is desirable in machines of this type toprovide electric motor operating mechanism in order to dispense with thehand operated crank which was formerly employed on machines of thistype. The motor mechanism which it is desired to use in connection withthe present machine is of a form which is old and well known inthe artand shown in Let tors Patent to Kettering No. 910,690, issued January26th, 1909, and reference may be had to the said patent for a detaildescription of the motor mechanism. By reference to said patent it willbe found that the m0- tor is not positively connected to the main driveshaft of the register, but a clutch connection is interposed between thetwo which plutch is controlled by the specialbr clerks eys.

In Fig. 11 is shown an improved form of controlling mechanism which isunder the control of the special keys for releasing the machine andclutch simultaneously. The

5 motor mechanism and the direct control of the keys over the clutchdoes not form a part of the present invention. Improved mechanism,however, is provided as shown in Fig. 11 whereby a second operation ofthe machine is prevented when one of the controlling keys is held in atthe end of a previous operation. It has been found that in practice thisis often attemptedby persons who attempt to misoperaite the machine tocover up adroit manipulations..- In these attempts it was customary topress in one of the controlling keys and hold said key depressed so thatat the end of the first operation the key could not come out to homeposition and would thereby hold the circuit for the motor closed,permitting an immediate second operation of the machine to destroy theindication of the first operation immediately. This would prevent thereading of the false indication by the customer or other persons in thestore. With the construction shown in Fig. 11 it is rendered necessaryto permit of the complete release of the controlling keys'andrestoration to normal position before a second operation of the machinemay be effected.

As hereinbefore stated, when one of the special keys 30 is depressed itwill raise its detent member 7 7 and allow the sliding locking plate 84to spring rearwardly beneath the lower forward end 83 of the detentmember 7 7 thereby locking the key in depressed position. The movementof the sliding member 84 rearwardly under the action of the spring isemployed to release the. motor mechanism. As shown in Fig. 11 only aportion of a clutch 142 is shown. This form of clutch has become wellknown in the art and it is not thought necessary to describe it indetail in the present application. For a detailed description of thesame reference may be had "to the patent above referred to. In this formof clutch-the member 142 is adapted to be given a slight preliminarymovement in a clockwise direction about. the shaft 143 under the actionof a coil spring, not shown, to render the clutch effective. The disk142 is,l1'owever,normally rest-rained from such movement by theengagement of a flange 144, carried by said disk 142, with a flange 145formed on one arm of a lever 146 pivoted at 147 to the frame of themachine. The lever 146 also carries a lug 148 which normally engages ashoulder 149 formed on a disk 150 fast on the shaft 48. As will be notedfrom the train of gearing from the clutch member to theshaft 48, theshafts 133 and 48 are adapted to be given a single r0tation at eachoperation of the machine. Gonnected to a downwardly extending arm 1.51of the lever 146 is a spring 152 which normally tends to rock the lever146 about its pivot 147 to withdraw the lug 148 from ongagement withshoulder 149 of disk 150 and also withdraw the flange 145 from the pathof the flange 144 carried by the clutch disk 142 thereby to render theclutch efiect-ive and release the motor and permit the operation of themachine. The movement of the lever 146 in this manner is prevented,however, by reason of the engagement of a lug 153, carried by saidlever, with a lug 154 carried by a lever 155 pivoted at 156 to the frameof the machine. A downwardly extending arm of the lever 155 is connectedby a link 157 to an arm 158 fast on a rock shaft 159. Fast on the rockshaft 159 adjacent the sliding locking plate 84 appropriate to the bankcontaining the special controlling keys, is an arm 160 pivoted at 161 tothe sliding rocking plate 84. When one of the keys is depressed and thesliding locking plate 84 is permitted to spring rearwardly under theaction of spring 86, said movement will, through the pivotal connection161with the lever 160, rock the shaft 159. The rocking movement of theshaft 159 will, through the medium of the arm 158 and link 157, rock.

the lever 155 about its pivot 156 to disengage the lug 154, carried bysaid lever, from the lug 153 formed on the lever'146. As soon as thisdisengagementis effected, the spring 152 will act to rock the lever 146about its pivot thereby releasing the operating mechanism ashereinbefore described. Upon the operation of the machine, when theshafts 133 and 48 are given a single rotation a pin 160 carried by thegear 161 fast on the shaft 133 will engage a flange 162 carried byrearwa'rd extending arm of the lever 146 thereby rocking the lever aboutits pivot 147 against the tension of the spring 152 and back to normallocking position. At this time in the operation of the machine the keyswill have been released and the sliding locking member 84 moved back tonormal forward position against the tension of the spring 86. When thesliding member 84 is so moved forwardly it will rock the shaft 159 in acounter-clockwise direction through the medium of the connectionshereinabove described. The rocking movement of the shaft 159 will tendto restore the lever 155 to normal position to again bring the lug 154carried thereby in the path of the lug 153 formed on the lever 146,thereby preparing the machine for the second operation.

Fast on the shaft 159 is an arm 163 which is pivotally connected at itsupper end to the slide 164 slotted and surrounding a pin 166 carried byan upwardly extending arm 16.7 formed on the lever 91 hereinbeforereferred to. The slide 164 is formed with a bevel lug 168 which normallyengages the pin 169 carried by a lever 170 pivoted at 171 to the frameof the machine. At its rear end the lever 170 is formed with a shoulder172 which is adapted to engage a lug 173 carried by the downwardextending arm of the lever 146. Such engagement, however,

is prevented by reason of the normal engage ment of the bevel lug 168 ofthe pin 169 at the forward end of the lever'170. A spring 174 tendsnormally to rock the lever 170130 cause the shoulder 175 to engage thelug 17 3. When a ke yfz is depressed as hereinbefore stated, and"itheslide 84 moves rearwardly'to rock the shaft 159, the slide 164 i will bedrawn rearwardly through its connections with the shaft l59rthereby withdrawing the bevel lug 168 from engagement with the pin 169, to permitthe lever'170 to rock about itsfpivot 171. The movement of the artsares'o timed, however, that this rocking movement of the lever 170 isnot permitted-until after the lever 155 has been rocked to release thelever 146. By this time the slide 84 will remain in its rearmostposition. This will continue the disengagement of the bevel lug 168 andpin 169 and consequently under the action of the spring 174 the shoulder175 will be held'in' engagement with the lug 173., At the end of theoperation,-however, the pin 160 carried by the disk 161'will engage theflange 162 carried by the lever 146'and thereby move lBV6I"14:6'"t0a-position slightly beyond its normal position; When the lever 146 is somoved the lug 173 will be moved beyond the shoulder 17 5 therebyreleasing the lever 17 0 and permitting the same to rock about its pivotunder the action'of the spring 174 to cause the shoulder 175 to rock upin front of the lug 173. This engagement of the shoulder and lug willprevent the movement of the lever 146 under the action of its spring 152again to release the machine although the lug 154 is held out ofengagementwith the lug 153 by reason of the previously depressed key beingheld in depressed position. It will therefore readily be seen that itwill be necessary to release the depressed kev before anotherv operationof the machine may be effected. The release of the depressed key, itwill be remembered, may be effected by the depression of the lever 91.This will, ashereinbefore stated,

effect the rocking movement of the shaft 90 and, through the medium ofthe pin 89 carried thereby and the pin 88 appropriate to the slide 84 ofthe special key bank draw said plate'84 forwardly to permit the detentmember 75 to drop down andirelease the depressed key. This forwardmovement of the plate 84 will, throughthe medium of the shaft 159 andinnections, again rock the plate l55fbaek -to -normal position to aplurality of totalizers, of actuating mechbring the lug 154 carriedthereby into the path of the lug 153 formed on the lever 146. \Vhen theshaft 159 is rocked to permit the operation just described, it will alsocause forwardly, the bevel lug 168 carried thereby will engage the pin16!) carried by the lever 170. Thus engagement of the lug 1.68 and pin169 will rock the lever 170 to an extent sullieient to disengage thenotch 172 from the lug 173, thereby permitting the lever 146 to move aslight distance under the impulse of its spring 152 to cause the lug 153to strike against the lug 154. The parts are then in a position topermit of a second complete operation of the machine if it is sodesired. Thus it will readily be seen that the improvements embodied inthe presend invention tend greatly to improve the t vpc of machine towhich they have been applied. By their application to this type ofmachine they have overcome many objectionable points which were mattersof considerable importance in the practical employment 0f the machine inthe performance of, its intended functions.
